Cummins • Perkins • VM V6 • VM four-cylinders
The first diesel engines used by Chrysler Corporation cars were Perkins models, used in trucks in the United States and worldwide. Chrysler International built cars with Perkins engines in Antwerp and then Rotterdam from 1956 to 1962. AMC Ramblers were fitted with similar Perkins engines; and many Chrysler Corporation cars were converted to diesels by Hunter NV, Perkins’ Belgium distributor.
After Dodge bought Commer, they would use Perkins diesel engines in their British-built trucks. (Perkins was purchased by Caterpillar in 1998 but still makes engines under its own name.) Chrysler opened their own diesel engine plant in 1963 in Darlington, UK, but sold it to Cummins in 1964.
Starting in 1978, Dodge packed a Mitsubishi diesel in its D100 pickups and Power Wagons. The engine was the Mitsubishi 6DR5, 3950 cc, with 105 hp at 3500 rpm; it was virtually identical to the Land Cruiser diesel engine of the time. The year this engine was dropped is unclear.
Cummins engines were first used in Dodge Rams in 1989; they were surprisingly popular from the start and may have single-handedly saved the company’s heavy-duty pickup line. These “B” engines were originally rated at 160 hp, with torque of 400 lb-ft at 1,700 rpm; the torque has been doubled since then.
Chrysler has used numerous VM Motori diesels in vehicles sold in Europe, as well as Jeeps sold in numerous regions. Chrysler also briefly used a Mercedes 3-liter V6 diesel, most notably in a limited edition Jeep Liberty, and in rebadged Freightliner/Mercedes Sprinter vans.
Chrysler had new VM Motori diesel engines for export markets in 1999. The 2.5 was for minivans and Jeeps, the 1.9 was for cars, and the 3.1 was for Jeeps; the smaller engines were direct-injected four-valve turbodiesels, released in 2001 (1.9) and 1999 (2.5), while the 3.1 liter was a five-cylinder. All had better performance, efficiency, and noise levels than the earlier models, and met Stage III emissions rules. They all had:
The engines were:
The Jeep Grand Cherokee, Jeep Commander, and Chrysler 300C had an optional new 3-liter Mercedes common-rail V6 diesel, with 2,000+ bar Bosch fuel injection, a variable geometry turbocharger, and four valves per cylinder; it met Euro 4 standards, using a particulate filter on the 300C. Maximum power was 160 kW (218 hp DIN) and peak torque was 510 N.m (376
lb.-ft.) at 1800 rpm. The engine was mated to a Mercedes W5A580 automatic transmission, and weighed 208 kg / 459 lb. Fuel consumption with the 300C was 8.1 L/100
km, EU standard for sedan (8.3 for touring).
The PT Cruiser used a variable geometry turbo, measuring 2.2 liters, generating 110 kW (150 hp) with the same gas mileage as the previous, less powerful unit (6.7 L/100 km,
combined cycle). Maximum torque of 300 Nm (221 lb.-ft) was produced from 1600
rpm to 3000 rpm. Matched to a five-speed manual transmission, this engine
reduced the 0-to-100 km/h acceleration time from 12.1 seconds in the
previous model to 10.8 seconds (estimated). The engine was an advanced
common-rail design, Euro 4 compliant, with less high-frequency combustion noise
than the previous diesel engine.
Horsepower ratings may vary from country to country and year to year. Lars noted that the 2005 2.5 VM engine is also sold with 120 hp (“negative chip tuning”).

1996-98 in Model GS with chains (thanks, Doug Hetrick);
1999-2000 in Model GS with timing gears. “The gear model started around Sept 1997. The only way to see which model is to look at the injection pump. The chain model has Bosch 0 460 404 975 while the gear model has Bosch 0 460 404 963.”
